Neutralization Activity: This antibody has been reported to be useful for the neutralization of recombinant human IL-2. Neutralization activity may be measured with a proliferation assay using 100 pg/mL recombinant human IL-2 (Cat. No. 554603) to stimulate CTLL-2 cells at 2x10^4 cells/mL as indicator cells (i.e. preincubation of the antibody with recombinant human IL-2 for 60 minutes). 50% Neutralization (ND50) at 0.1-1.5 µg/mL >95% Neutralization at 3 - 15 myg/mL
Purification
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

The MQ1-17H12 antibody reacts with human interleukin-2 (IL-2). The immunogen used to generate the MQ1-17H12 hybridoma was recombinant human IL-2. Unconjugated or purified forms of this antibody have been reported to be neutralizing for human IL-2 bioactivity.
